Reinforcement structure for sun tent extension canopy

ABSTRACT

A reinforcement structure for sun tent extension canopy is formed with a pair of extension frames extending from the top ends of the awning poles of the tent. Each extension frame is composed of an extension pole, a supporting pole, a reinforcing pole and clamps, wherein the extension pole has one end connected to the top end of the awning pole while the other end is connected to the supporting pole which has its other end connected to the awning pole. The extension pole comprises a pair of clamps and a receptacle which is to receive one end of the reinforcing pole which has its other end connected to another receptacle on a side pole in order to support the tent when a canopy is covered thereon.

FIELD OF THE INVENTION

[0001] This invention relates to a reinforcement structure for sun tentextension canopy, more particularly to a structure to support a canopyextending from the tent.

[0002] Due to the busyness and tension of our daily life, outdooractivities have been popular for many people and families to relax theirstress from work and also to have a chance to breathe the natural air.However, many of the outdoor facilities have no roof or covers, peoplehave to either stay under the sun or bring their tent to provide a shadyarea.

[0003] A conventional tent can cover a limited area only and it mayshake when the wind blows. In view of this, the inventor has inventedthe present invention to improve the shortcomings.

SUMMARY OF THE INVENTION

[0004] It is the primary object of the present invention to provide areinforcement structure for sun tent canopy, which is steady under wind.

[0005] It is another object of the present invention to provide areinforcement structure for sun tent canopy, which is easy to installand to dismount.

[0006] It is a further object of the present invention to provide areinforcement structure for sun tent canopy, which is inexpensive inmanufacture.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0015] A reinforcement structure for sun tent canopy of the presentinvention, as shown in FIGS. 1 and 2, comprises a pair of extensionframes 2 connected to the top of two sides of the awning poles 11 of thetent 1. Each extension frame 2 is composed of an extension pole 21, asupporting pole 22, a pair of clamps 23 and 24 and a reinforcing pole 4.

[0016] Each extension pole 21 has one end connected to the top end ofthe awning pole 11 while the other end of which is connected to an endof the supporting pole 22 which then has its other end connected to thepole 11. In such way that the extension pole 21, the pole 11 and thesupporting pole 22 forms a triangle to support the extension pole 21,which is secured with the a pair of clamps 23 and 24 at center portionfacing outwardly thereof. A receptacle 3 is formed inward of theextension pole 21 with a socket 31 thereat for receiving another end ofthe reinforcing pole 4. For the reinforcing pole 4 to insert with oneend therein, the reinforcing pole 4 has a stretch cord 5 which connectsthe reinforcing pole 4 to the socket 31, as shown in FIG. 3. Anotherreceptacle 3A is formed on a side pole 12 inwardly corresponding to thereceptacle 3 on the extension pole 21.

[0017] To assemble, the two ends of the reinforcing rod 4 are insertedinto the sockets 31 and 31A of the receptacles 3 and 3A, respectively.The extension pole 21 is stretched so that when a canvas 14 is placed onthe extension poles 21, the canvas 14 will remain in a flat and stretchstatus. Whereas the reinforcing pole 4 will hold the canvas 14 at placeand prevent the canvas 14 from retreating back to its original position.

[0018] To fold the canopy 14, as shown in FIGS. 3 and 4, the reinforcingpoles 4 is dismounted from the receptacle 3 and is tied to the extensionpole 21 with the stretch cord 5, whereas the reinforcing poles 4 issecured by the clamps 23 and 24 as well. FIG. 5 has shown a folded tentthat the extension pole 21 and the supporting pole 22 are both foldedtowards the awning pole 11 of the tent 1.

[0019] Another embodiment is shown as FIGS. 6 and 7, wherein the sidepole 13 replaces the side pole 12 of the above. The reinforcing pole 4with the stretch cord 5 is secured at its two ends to the sockets 31 and31B of the receptacles 3 and 3B of the extension poles 21 and the sidepole 13. To dismount, as shown in FIG. 8, the two ends of thereinforcing pole 4 are retracted from the receptacles 3 and 3B, due tothe stretch cord 5 is connected to the receptacles 3 and 3B, thereinforcing pole 4 will be located next to the awning pole 11. To mountthe tent 1, the extension frame 2 and the side poles 12 and 13 arestretched, and then the reinforcing pole 4 is inserted into the tworeceptacles 3 and 3B.

I claim:
 1. A reinforcement structure for sun tent extension canopycomprising a pair of awning poles covered with a canopy, and a sidepole, each said awning pole having a extension frame at the top portionthereof, each said extension frame comprising an extension pole, asupporting pole, a reinforcing pole and clamps, wherein said extensionpole having one end connected to the top portion of said awning pole,and said supporting pole having also one end connected to the lowerportion of said awning pole, and the improvements comprising saidextension pole comprising a pair of clamps and a receptacle, said sidepole comprising also a receptacle corresponding to said receptacle ofsaid extension pole, said reinforcing pole comprising a stretch cordadapted to connect to said receptacles; by means of inserting the twoends of said reinforcing pole into said receptacles of said extensionpole and said side pole to reinforce the extension canopy fromretracting, and said stretch cord of said reinforcing pole being adaptedto tie said reinforcing pole to said extension pole with clamps whenfolding said tent to prevent said reinforcing pole from disappearing. 2.The reinforcement structure for sun tent extension canopy, as recited inclaim 1, wherein said reinforcing pole comprises stretch cords at bothends to be tightened to said two receptacles, and to tie saidreinforcing pole on said side pole when folding said tent.
